It would be nice if the commit message would address the confusion that
was indicated in our earlier discussion. That is, it's not interesting
*if* a profile consists of output and input parts, but *what* outputs
and inputs the profile consists of. The "if" question is already
answered by n_sinks and n_sources.

The comment still doesn't explain how the strings are supposed to be
generated and used. That said, I don't really care that much, since I'm
planning to soon change these struct fields anyway.
